4: Ibérco Pork and Foie Gras burger at Opera Tavern (£8)
This is a burger for foodies. What it lacks in size it makes up for in flavour. Using top quality Ibérico pork, head chef Jamie Thicket adds foie gras shavings to the patties, which gives the meat a divine richness, juiciness and depth of flavour.
And if that wasn’t enough, the tiny morsels are also stuffed with melted aged manchego cheese, lettuce, homemade onion jam, crispy red onions and aioli. Served in soft brioche buns, the sliders come with hot, sweet pickled chilis. They had us at foie gras.
